if you run this code, you get the first result([1,2,[3,4]]), but if you print this in html, you see as the second result. You can try to see it in console.log In this JSFiddle you can try it: (see the console log)

  var x = [1,2];
  var y = [3,4];
  console.log(x); //here prints in the console the [1,2,[3,4]]
  document.getElementById('result').innerHTML=x; //here prints in the html the [1,2,3,4]
